The minimum weight can be improved by the following measures:
- Selecting suitable weighing parameters
- Choosing a better location
- Using smaller taring containers
- Using an inner draft shield (AX)
The information contained in this document has been carefully prepared and represents the most up-to-date status. Data shown as typical are reference values
for calculation of the expected measurement uncertainty. The actual measurement performance may be affected negatively or positively by the place of use and/
or the settings.
